CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of and claims the benefit of priority to U.S. patent application Ser. No. 11/443,543, filed on May 30, 2006, entitled “System, Method And Computer Instructions For Aiding Image Analysis”, which is herein incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

The present invention generally relates to systems, methods and computer instructions for aiding image analysis. More particularly, the present invention relates to systems, methods and computer instructions for aiding image analysis by providing a link to information regarding an image that is similar to an image that is being analyzed.

Images can be used to aid in the monitoring and/or diagnosis of ailments. Such images are created using imaging systems. Two types of imaging techniques utilized by imaging systems are Computed Tomography (CT) imaging and/or Magnetic Resonance (MR) imaging, for example. Images collected using an imaging system are referred to collectively as an imaging study. Once an imaging study is completed, the images therein can be displayed on a workstation, such as a Picture Arching and Communicating System (PACS) workstation, for example.

When an image is presented for review, a certain portion of the image can be considered interesting because, for example, that portion of the image could indicate abnormality. Abnormality in an image could indicate a certain disease, also known as, pathology. Thus, once abnormality is discovered, it is desirable to identify and diagnose the pathology that could be causing the abnormality.

People that review medical images, such as radiologists, for example, usually rely on past training and/or individual research in order to identify and diagnose pathology. Sometimes pathology is readily identified and diagnosed. However, when there is difficulty identifying and diagnosing unfamiliar pathology, time can be spent manually researching in order to identify and diagnose pathology. Further, mistakes can be made when identifying and diagnosing unfamiliar pathology.

There are systems that incorporate what is known as Computer Aided Diagnosis (CAD), which can aid in the identification of areas of interest in an image and mark such areas so that a user that is reviewing the image is alerted to the area. Further, systems that incorporate CAD can suggest pathology based on a comparison of the image to previously analyzed images. However, systems that incorporate CAD can provide false positives, that is, systems that incorporate CAD can falsely mark an area of an image as an area of interest when there is no pathology in that area of the image. Thus, although systems that incorporate CAD may be effective when pathology is readily identified and diagnosed, if there is difficulty identifying and diagnosing unfamiliar pathology, a person reviewing an image can still spend time manually researching in order to identify and diagnose pathology.

Thus, there is a need for a system, method and computer instructions for aiding image analysis that provides improved and/or streamlined identification and diagnosis of pathology in an image used in a medical examination.

The system 100 can also be implemented in many ways. For example, the system 100 can be integrated with existing applications that run on a Microsoft® platform and/or other platforms as an add-on product. In one implementation, the system 100 can be integrated with a workstation(s) that is connected to a HIS and/or a RIS, such as a PACS workstation, for example. Other desirable ways to implement the system 100 may exist, as known to those skilled in the art.

In operation, an embodiment of the system 100 can be implemented in connection with a HIS and/or a RIS, for example. In such an embodiment, the input module 102 can be configured to input an image from an image review station, such as a PACS workstation, for example. For example, an image of a spine can be input into the image review workstation. The user of the image review workstation can then identify an area of the image that may contain an abnormality. For example, the user of the image review workstation could identify an area of the image that contains a separation in the spine. The image could then be cropped to create a new image that is focused on the spine separation. The new image can be input into the input module 102. The search module 104 could then search images accessible on a HIS, a RIS and/or the Internet to locate an image(s) that is similar to the input image. In an embodiment, image information, such as, modality information, body part information, contrast agent information and/or other DICOM header information, for example, can also be input into the input module 102, and the search module 104 can restrict searches for images based on the image information. When an image that is similar to the input image is found, a link to the information regarding the located image can be output via the output module 106. For example, a link to a previous image analysis, an article, a report and/or a web page can be output as a visual display to an image review workstation, such as a PACS workstation, for example. In this example, where the input image includes a spine separation, links that could be output include: a link to a previous image analysis where a spine separation was diagnosed as a fracture; a link to a previous image analysis where a spine separation was diagnosed as a hairline fracture; a link to a previous image analysis where a spine separation was diagnosed as a rupture; a link to a report/article regarding Orthopedic Guidelines; a link to the web page ehealth.com; a link to a lab report for Calcium; a link to prior CT images; and/or a link to prior MR images, for example. After the links are output, a user of the image review station can review the information by selecting the links. If the user of the image review station is not ready to make a diagnosis, the communication module 108 can output the input image and the located information and receive a responsive communication via a collaboration system that uses an instant messenger-like service or chat-room-like format to circulate an input image and located information and allow for a response to be provided, for example. When the user of the image review station is ready to make a diagnosis, the user can input image analysis information into the analysis input module 110. For example, the user can input image analysis or annotation information that includes an image(s), text and/or audio into the analysis input module 110. For example, the user can input: the input image as input and/or with markings on the image; other images that were included with the located information; typed or written text created by the user of the image review station; text that was included with the located information; audio created by the user of the image review station; and/or audio that was included with the located information. Once the analysis information has been input, the storage module 112 can store the analysis information. For example, the storage module 112 can store the analysis information in: a database that is part of a RIS; a database that is part of a HIS; a database that is accessible via the Internet; a local database; and/or any database that is in networked communication with the storage module 112.

In operation, another embodiment of the system 100 can be implemented in connection with a HIS and/or a RIS, for example. In such an embodiment, the input module 102 can be configured to input an image from a system that incorporates CAD. For example, an image of a kidney can be input into a system that incorporates CAD. The system that incorporates CAD can then identify an area of the image that may contain an abnormality. For example, the system that incorporates CAD could identify an area of the image that contains a mass on the kidney. The image could then be cropped to create a new image that is focused on the kidney mass. The new image can be input into the input module 102. The search module 104 could then search images accessible on a HIS, a RIS and/or the Internet to locate an image(s) that is similar to the input image. In an embodiment, image information, such as, modality information, body part information, contrast agent information and/or other DICOM header information, for example, can also be input into the input module 102, and the search module 104 can restrict searches for images based on the image information. When an image that is similar to the input image is found, a link to the information regarding the located image can be output via the output module 106. For example, a link to a previous image analysis, an article, a report and/or a web page can be output as a visual display to an image review workstation, such as a PACS workstation, for example. In this example, where the input image includes a kidney mass, links that could be output include: a link to a previous image analysis where a mass on a kidney was diagnosed as a tumor; a link to a previous image analysis where a mass on a kidney was diagnosed as a cyst; a link to a previous image analysis where a mass on a kidney was diagnosed as a malignant tumor; a link to a report/article regarding Sloan Kettering Guidelines; a link to a report/article regarding the American Cancer Society; a link to the web page mayo.com; a link to a lab report for Creatinine; a link to a lab report for Hematocrit; a link to a lab report for Gleason's Score; and/or a link to a lab report for PH Value, for example. After the links are output, a user of the image review station can review the information by selecting the links. Then the user can communicate with patrons of a collaboration system via the communication module 108 and/or input analysis information via the analysis input module 110 as described above with regard to the spine example. Once analysis information is input, the storage module 112 can store the analysis information as described above with regard to the spine example.

In operation, another embodiment of the system 100 can be implemented in connection with a HIS and/or a RIS, for example. In such an embodiment, the input module 102 can be configured to input an image from an image review station, such as a PACS workstation, for example, after the image has already been analyzed by a system that incorporates CAD. For example, an image of a breast can be input into the image review workstation from a system that incorporates CAD. The user of the image review workstation can review the image and decide whether the portion of the image that was identified by CAD as containing an abnormality, such as a lump, is the portion of the image that should be analyzed. If the user of the image review workstation agrees with the CAD analysis, the image could then be cropped to create a new image that is focused on the lump. If the user of the image review workstation does not agree with the CAD analysis, the user of the image review station can select a different portion of the image that the user believes contains an abnormality, such as a lump, and the image can be cropped to create a new image that is focused on the abnormality. The new image can be input into the input module 102. The search module 104 could then search images accessible on a HIS, a RIS and/or the Internet to locate an image(s) that is similar to the input image. In an embodiment, image information, such as, modality information, body part information, contrast agent information and/or other DICOM header information, for example, can also be input into the input module 102, and the search module 104 can restrict searches for images based on the image information. When an image that is similar to the input image is found, a link to the information regarding the located image can be output via the output module 106. For example, a link to a previous image analysis, an article, a report and/or a web page can be output as a visual display to an image review workstation, such as a PACS workstation, for example. In this example, where the input image includes a lump in a breast, links that could be output include: a link to a previous image analysis where a lump in a breast was diagnosed as a cyst; a link to a previous image analysis where a lump in a breast was diagnosed as a fibroid cyst; a link to a previous image analysis where a lump in a breast was diagnosed as scar tissue; a link to a report/article regarding Cysts; a link to a report/article regarding the JAMA; a link to the web page bCancer.com; and/or a link to the web page eMed.com, for example. After the links are output, a user of the image review station can review the information by selecting the links. Then the user can communicate with patrons of a collaboration system via the communication module 108 and/or input analysis information via the analysis input module 110 as described above with regard to the spine example. Once analysis information is input, the storage module 112 can store the analysis information as described above with regard to the spine example.

FIG. 2 illustrates a method for aiding analysis of an image 200 used in accordance with an embodiment of the present invention. At 202, an image is input. For example, an image can be a portion of an image that a user of an image review workstation, such as a PACS workstation, for example, and/or a system that incorporates CAD has identified as possibly including pathology. At 204, information regarding an image that is similar to the input image is located. For example, information can be located that is accessible on a HIS, a RIS and/or the Internet. Also, in an example, locating information can include using an image recognition algorithm to identify previously analyzed images that are similar to the input image. Also, in an example, image information, such as, modality information, body part information, contrast agent information and/or other DICOM header information, for example, can also be input, and used as a basis for restricting a search for information regarding an image that is similar to the input image. Also, in an example, located information can include a previous image analysis, an article, a report and/or a web page. At 206, a link to the located information is output. For example, a link to the located information can be output as a visual display to an image review station, such as a PACS workstation, for example. At 208, the input image and the located information are output and a responsive communication is received. For example, the input image and the located information can be output and a responsive communication can be received via a collaboration system that uses an instant messenger-like service or chat-room-like format to circulate information and allow for a response to be provided, for example. At 210, an analysis of the input image is input. For example, an analysis of the input image can be input as an image(s), text and/or audio at an image review workstation, such as a PACS workstation, for example. At 212, the analysis of the input image is stored. For example, the analysis of the input image can be stored in: a database that is part of a RIS; a database that is part of a HIS; a database that is accessible via the Internet; a local database; and/or any database that is in networked communication.

Due to the many types of pathology that exist, identifying and diagnosing pathology shown in an image used in a medical examination can be difficult and time consuming. Applying the method 200, as described above and/or in light of the description of FIG. 1, may provide improved and/or streamlined identification and diagnosis of pathology in images used in a medical examination.
